Identification and characterization of a murine receptor for galactose‐terminated glycoproteins

Wanjin Hong, Anh Van Le, Darrell Doyle – 1 May 1988 – The asialoglycoprotein receptor, the hepatic binding lectin for galactose‐terminated glycoproteins, has been isolated and characterized from human, rabbit and rat liver. Several recent studies have shown the existence of the same receptor in murine liver. However, the biochemical structure of the receptor in murine liver has not been resolved. In this paper, we describe the identification and purification of the receptor for asialoglycoproteins from murine liver.

Interaction of woodchuck hepatitis virus surface antigen with hepatocyte plasma membrane in woodchuck chronic hepatitis

Tomasz I. Michalak, Norma D. Churchill – 1 May 1988 – The extent of association between woodchuck hepatitis virus surface antigen and host hepatocyte plasma membrane in chronic hepatitis was studied. Purified membranes containing the antigen were treated with various agents which perturb plasma membrane constituents to elute woodchuck hepatitis virus surface antigen. The products from disrupted membranes were analyzed by sedimentation in sucrose gradients and tested to identify the antigen reactivity.

Ectopic soft tissue calcium deposition following liver transplantation

Santiago J. Munoz, Steven B. Nagelberg, Paul J. Green, John D. Angstadt, Shuin L. Yang, Bruce E. Jarrell, Willis C. Maddrey – 1 May 1988 – We observed ectopic soft tissue calcification affecting seven patients following orthotopic liver transplantation. The cause of such calcification is unknown, but potential pathogenetic factors include hyperparathyroidism, calcium administered during and following surgery, renal failure, acid‐base changes and citrate in fresh frozen plasma.

Expression of class I and class II major histocompatibility complex antigens on human hepatocytes

Alessandra Franco, Vincenzo Barnaba, Piergiorgio Natali, Clara Balsano, Antonino Musca, Francesco Balsano – 1 May 1988 – We analyzed whether normal human hepatocytes, which normally do not display Class II major histocompatibility complex antigens, can be induced to express them in vitro, and whether this induction has an in vivo counterpart in chronic liver diseases. While both α‐ and γ‐interferon induced expression of Class I antigens, only γ‐interferon induced expression of Class II antigens on hepatocytes in vitro.

Quantitative importance of the 25‐hydroxylation pathway for bile acid biosynthesis in the rat

William C. Duane, Ingemar Björkhem, Jan Neal Hamilton, Susan M. Mueller – 1 May 1988 – During biosynthesis of bile acid, carbons 25–26–27 are removed from the cholesterol side chain. Side‐chain oxidation begins either with hydroxylation at the 26‐position, in which case the three‐carbon fragment is released as propionic acid, or with hydroxylation at the 25‐position, in which case the three‐carbon fragment is released as acetone.

Nuclear antigens reacted with sera and ascites of hepatocellular carcinoma patients

Yi‐Ming Chen, Cheng‐Po Hu, Pao‐Huei Chen, Ming‐Huey H. Chu, Yang‐Te Tsai, Shou‐Dong Lee, Chungming Chang – 1 May 1988 – In order to study hepatocellular carcinoma‐associated antigens, screening of sera and ascites was done from hepatocellular carcinoma patients having antibodies reactive with three hepatocellular carcinoma cell lines (PLC/PRF/5, Hep 3B and HA22T/VGH). The indirect immunofluorescent antibody test was used.

Ventricular function in cirrhosis and portasystemic shunt: A two‐dimensional echocardiographic study

Helmut Keller, Vera Bezjak, Beatrice Stegaru, Jan Buss, Eggert Holm, Dieter L. Heene – 1 May 1988 – Cardiovascular alterations such as increased heart rate, high cardiac output, reduced systemic vascular resistance, and in most of the cases, increased contractility parameters have been recognized in patients with advanced liver disease.

Amiodarone‐induced hepatic phospholipidosis: Correlation of morphological and biochemical findings in an animal model

Mauro Pirovino, Otfried Müller, Thomas Zysset, Ueli Honegger – 1 May 1988 – Morphological and biochemical investigations were performed in guinea pigs after 1, 3, 5 and 16 weeks of amiodarone feeding. The most prominent morphological finding was an increase in dense bodies in hepatocytes, Kupffer cells and in bile duct epithelia, reaching a maximum after 5 weeks of treatment according to morphometric analysis. Similar time courses were observed for the serum and liver tissue concentrations of amiodarone and desethylamiodarone and the—albeit minimal—extent of hepatocellular necrosis.

Early midzonal cell death during low‐flow hypoxia in the isolated, perfused rat liver: Protection by allopurinol

Mark E. Marotto, Ronald G. Thurman, John J. Lemasters – 1 May 1988 – Trypan blue uptake and lactate dehydrogenase release were measured as indices of irreversible cell damage in isolated, perfused rat livers during low‐flow hypoxia. In livers from fasted rats perfused in the anterograde direction, trypan blue uptake took place beginning at about 45 min of hypoxia. Cells which took up trypan blue first were located in narrow bands at the border between anoxic pericentral areas and normoxic periportal regions of the liver lobule.
